【摘要】：碳酸鹽巖油氣藏在全球范圍內分布廣泛,統(tǒng)計世界上236個大型油氣田,96個為碳酸鹽巖油氣藏,約占40%,而且儲量規(guī)模大、產(chǎn)量高的油氣藏多為碳酸鹽巖油氣藏,其儲量約占總儲量的50%左右,產(chǎn)量約占總產(chǎn)量的65%,碳酸鹽巖油藏中有30%以上為裂縫-溶洞型油藏,該類油藏的主要儲集空間以構造變形產(chǎn)生的構造裂縫與巖溶作用形成的孔、洞、縫為主,其中大型洞穴是最主要的儲集空間,裂縫既是主要的儲集空間,也是主要的滲流通道。在我國,這類油藏也有著廣泛的分布,自20世紀70年代以來,我國在勝利油田、華北油田和遼河油田相繼發(fā)現(xiàn)和開發(fā)了三十多個碳酸鹽巖潛山油藏,上個世紀九十年代末發(fā)現(xiàn)了塔河油田。我國海相碳酸鹽巖油氣資源量大于300×108t油當量,石油資源量約150×108t,主要分布在塔里木和華北地區(qū),但探明率僅8%。其中縫洞型油藏占探明儲量的2/3,是今后增儲的主要領域。油藏裂縫與巖塊間三相滲流機理的研究也越來越完善和深入,專家們在進一步研究上述機理的基礎上也進行了許多基本概念的研究,如滲吸采收率、滲吸半衰期、滲吸速度、巖塊采出程度與時間的關系等,這些在實驗室中得到的機理大多得到了現(xiàn)場資料和經(jīng)驗的驗證。國內方面,隨著20世紀70年代以來對國內碳酸鹽巖油藏的開發(fā),經(jīng)歷了邊實踐、邊認識、邊開發(fā)、邊調整的歷程,在油田開發(fā)上做了大量的工作,積累了豐富的經(jīng)驗,特別是任丘油田迷霧山組油藏的開發(fā)水平已經(jīng)進入國外同類油田開發(fā)的先進行列。
[Abstract]:Carbonate oil and gas reservoirs are widely distributed around the world, with 236 large oil and gas fields in the world and 96 carbonate reservoirs, accounting for about 40% of the oil and gas reservoirs, with large reserves and more carbonate reservoirs with high yields. The reserves account for about 50% of the total reserves, accounting for about 65% of the total production, and more than 30% of the carbonate reservoirs. For the fractured and cave type reservoir, the main reservoir space of this type of reservoir is mainly composed of structural fractures and karst formation, holes, holes and seams, among which large caves are the main reservoir space, and the cracks are both main reservoir spaces and main seepage passages. In China, these types of reservoirs also have extensive distribution from 20. Since the 70s of the century, more than 30 carbonate Qianshan reservoirs have been discovered and developed successively in Shengli Oilfield, North China and Liaohe oil fields, and Tahe oil field was discovered at the end of 90s of last century. The oil and gas resources of marine carbonate rocks in China are more than 300 x 108t oil equivalent, and the amount of stone oil resources is about 150 * 108t, mainly in Tarim and in Tarim. In North China, the exploration rate is only 8%. of which the fractured hole type reservoir accounts for the 2/3 of the proven reserves. It is the main area to increase the reservoir in the future. The study of the three phase seepage mechanism between the reservoir cracks and the rock block is becoming more and more perfect and deep. Most of the mechanisms obtained in the laboratory have been verified by field data and experience. At home, with the development of domestic carbonate reservoirs in China since 1970s, the process of border practice, edge development and edge adjustment has been developed in the field of oil field development. A lot of work has been done and rich experience has been accumulated. Especially, the development level of the haogshan reservoir in the Renqiu oilfield has already entered the advanced ranks of the foreign oil fields of the same kind.
